Answer 1

B. Its nectar tube was a foot long.

Darwin found the length of the nectar tube of the Star Orchid (Angraecum sesse) particularly interesting because he postulated that there must be a moth with a long proboscis capable of reaching the nectar deep within the tube. This led to his theories on co-evolution and the relationship between species.
